DETAILED DESCRIPTION

Embodiment 1

Referring to FIG. 1 and FIG. 4, an acousto-optic audio signal cable 36 according to a first embodiment includes an acousto-optic controller 20, an audio wire cluster, a set of light emitting diode (LED) marquee light wires 50, a first terminal 17, a second terminal 18, and a transparent insulating layer 26. The audio wire cluster includes a plurality of audio cables that are mutually twisted or disposed in parallel. An input end of the acousto-optic controller 20 is coupled to an end of the audio wire cluster and an end of the LED marquee light wire, respectively. An output end of the acousto-optic controller 20 is coupled to the second terminal 18. The other end of the audio wire cluster is coupled to the first terminal 17. The transparent insulating layer 26 wraps the audio wire cluster and the LED marquee light wire.
Specifically, the acousto-optic controller 20 includes a housing 19, a main circuit board 10 disposed in the housing 19, and a power supply/charging external socket 16 embedded in the housing 19. The main circuit board 10 includes a sampling amplifier circuit component 11, an analog-digital conversion circuit component 12, a microprocessor 13, a direct current (DC) output driver 14, and a power circuit component 15. An output terminal of the sampling amplifier circuit component 11 is coupled to an input terminal of the analog-digital conversion circuit component 12. An output terminal of the analog-digital conversion circuit component 12 is coupled to an input terminal of the microprocessor 13. An output end of the microprocessor 13 is coupled to an input terminal of the DC output driver 14. The power circuit component 15 is electrically coupled to the sampling amplifier circuit component 11, the analog-digital conversion circuit component 12, the microprocessor 13 and the DC output driver 14, respectively, and provides stable current for the sampling amplifier circuit component 11, the analog-digital conversion circuit component 12, the microprocessor 13, and the DC output driver 14. The power supply/charging external socket 16 is coupled between the power circuit component 15 and an external power source, and provides power for the power circuit component 15 to charge the power circuit component 15. The DC output driver 14 includes a DC positive-electrode output terminal 410 and three DC negative- electrode input terminals 411, 412 and 413.
The audio wire cluster includes a plurality of audio wires that are mutually twisted or disposed in parallel. In the present embodiment, optionally, the audio wire cluster includes three sets of signal conductors 21, 22, 23 and a set of ground conductors 24. Optionally, each set of signal conductors is composed of a plurality of metal insulated conductors with low impedance as well as high conductivity. One end of each set of audio cables is coupled to the first terminal 17 and the other end thereof is coupled to the input terminal of the sampling amplifier circuit component 11. The sampling amplifier circuit component 11 receives an electrical signal from the audio cable. In addition, the output terminal of the sampling amplifier circuit component 11 is coupled to the second terminal 18 through the second set of the audio cables. In the present embodiment, optionally, the second set of audio cables includes three sets of signal conductors 21, 22, 23 and a set of ground conductors 24. Further, the second set of audio cables are coupled to the audio cables at the input terminal of the sampling amplifier circuit component 11 inside the sampling amplifier circuit component 11 in a one-to-one manner. Voice signal is transmitted by the second set of audio cables to an amplifier equipment through the second terminal 18.
The LED marquee light wire includes a plurality of surface-mounted LED lights 001, 002, 003, two or three positive copper conductors 110, 114 and three negative copper conductors 111, 112, 113. One end of each of the two or three positive copper conductors 110 and 114 is coupled to the DC positive output terminal 410 of the DC output driver 14. The other end of each of the two or three positive copper conductors 110 and 114 extends along the audio wire cluster. One end of each of the three negative copper conductors 111, 112, and 113 is coupled to each of three DC negative input terminals 411, 412, 413 of the DC output driver 14 in a one-to-one manner. The other end of each of the three negative copper conductors 111, 112, and 113 extends along the audio wire cluster. One of the positive copper conductors 110 and 114 and one of the negative copper conductor 111, 112 and 113 form a conduction loop with a light string including a set of surface-mounted LED lights 001, 002 and 003. Alternatively, one of the positive copper conductors 110 and 114 and two of the negative copper conductors 111, 112, and 113 arranged at opposite sides of the one of the positive copper conductors 110 and 114 may form conduction loops with a light string including two sets of surface-mounted lights 001, 002 and 003. The surface-mounted LED lights 001, 002, 003 in each conduction loop are composed of at least three surface-mounted LED light beads. Each of the surface-mounted LED lights 001, 002 and 003 is respectively fillet-weld between one of the positive copper conductors 110 and 114 and one of the negative copper conductors 111, 112 and 113 adjacent the one of the positive copper conductors 110 and 114 at a preset interval along a preset direction. Each of the surface-mounted LED light beads is electrically coupled to the DC output driver 14 through one of the positive copper conductors 110 and 114 and one of the negative copper conductors 111, 112, and 113, and then emits light sequentially.
Each of the audio wires is wrapped with a metal woven mesh shield layer 27. The transparent insulating layer 26 wraps an integrated wire cluster of the audio wire cluster and the LED marquee light wire.
Further, the metal woven mesh shield layer 27 may be replaced with an aluminum foil shield layer. Both the aluminum foil shield layer and the metal woven mesh shield layer 27 are able to enhance an anti-interference ability of the audio cable.
When used, the first terminal 17 is coupled to an audio equipment and the second terminal 18 is coupled to an amplifier equipment. When the audio equipment makes sounds, the sound transmitted by the audio wire is output through the amplifier equipment. Further, the sampling amplifier circuit component 11 samples an acoustic electrical signal from the audio wires, and transmits the acoustic electrical signal to the analogue-digital conversion circuit component 12. The acoustic electrical signal is converted into a digital signal by the analog-digital conversion circuit component 12. The digital signal is transmitted to the microprocessor 13, then is converted into a pulse signal and then is output to the DC output driver 14. The DC output driver 14 controls the LED marquee lights to produce regular flash of light or produce a flow of light in sequence according to the received pulse signal command.
In the microprocessor 13, a specific conversion correspondence between the digital signals and pulse signals has been set in advance. Thus, a flash effect or a chasing in sequence as running water effect corresponding to each sound can be produced. In this way, the light effect produced by the acousto-optic audio signal cable corresponding to each sound in the audio can be characterized.
In the present embodiment, the second terminal 18 is directly coupled to the acousto-optic controller 20 and the housing 19. As shown in FIG. 7, the second terminal 18 may be coupled to an end of another segment of the acousto-optic audio cable, or as shown in FIG. 6, the second terminal 18 may be directly coupled to the terminal of the audio signal cable.

Embodiment 2

As shown in FIG. 2 and FIG. 3, acousto-optic audio signal cables 37 and 38 are similar to that in the first embodiment. The differences lie in that in the LED marquee light wire in the embodiment 2, five parallel copper wires attached with LED lights can form three pairs of LED emitting wires, the three pairs of LED emitting wires can be would in a spiral at a certain twist pitch at one side of the audio wire cluster, or would in a spiral on an outer wall of the audio wire cluster, thereby forming a LED marquee light acousto-optic audio signal cable. One end of the cable is coupled to the DC output driver 14 and is disposed in the transparent insulating layer 26. The regular flash of light or a flow of light produced by the cable can be presented through the transparent or light-transmitting insulating layer 26. Because the copper wires of the acousto-optic audio signal cable are would in a spiral, the cross-sectional area of the whole acousto-optic audio signal cable can be small, thus the acousto-optic audio signal cable can afford a large enough pull force and can be flexible.

Embodiment 3

As shown in FIG. 5, an acousto-optic audio signal cable 39 is similar to that in the embodiment 1. The differences lie in that there is only one set of LED marquee light. The LED marquee light includes surface-mounted LED lights 001, 002 and 003 as well as a flexible printed circuit (FPC) board 28. A cross-sectional area of the single set of LED marquee light acousto-optic cable is small, and a cost of the acousto-optic cable is low. However, the whole acousto-optic audio signal cable can produce light effect from 180° directions in a cross-section of the acousto-optic audio signal cable, and may produce a shadow.

Embodiment 4

As shown in FIG. 8, an acousto-optic audio signal cable 40 is similar to that in Embodiment 1. The differences lie in that there are two sets of LED marquee light wires in embodiment 4, and each set includes surface-mounted LED lights 001, 002 and 003 as well as a FPC board 28. The two sets of LED marquee light wires are juxtaposed on the audio wire cluster, and are coupled to the DC output driver 14, respectively. The positive copper conductors 110, 114 can be replaced by an ordinary printed positive circuits, and the negative copper conductors 111, 112, and 113 can be replaced by an ordinary printed negative circuits. This structure doubles a light emitting area of the entire acousto-optic audio cable. Thus, the whole acousto-optic audio signal cable can produce light effect from 360° directions in a cross-section of the acousto-optic audio signal cable without any shadow, which is quite bright and beautiful. Further, because the two sets of LED marquee light wires and the audio wire juxtaposed with the two sets of LED marquee light wires are wrapped in the transparent insulating layer 26, thus the marquee and flashing light effect can be presented through the transparent insulating layer 26.
On the basis of the embodiment 3, it will be apparent for those skilled in the art that three or more sets of LED marquee lights wires can be disposed on the audio wire cluster. This modification or replacement falls within the scope of the claims and within the scope of equivalent technical solutions of the present disclosure.
